Executive summary This clip from our workshop shows our automatic wire coil packing machine. A flat-lying steel wire coil runs in on rollers, the ring turns through the coil eye and lays blue film round the whole coil section, and the wrapped coil runs out. Our FPW-AU300 takes coils of 300–1,500 kg and 500–1,200 mm OD. Below we cover the cycle, the published data and a worked example for overlap and ring turns.

What the clip shows
The clip is filmed in our workshop around a green wire coil packing machine.
| Step | What you see |
|---|---|
| Infeed | A bare steel wire coil lies flat on the infeed roller conveyor |
| Positioning | The coil is pushed into the wrapping station between upright side rollers |
| Wrapping | The ring turns through the coil eye and blue stretch film is applied over the whole coil cross-section |
| Outfeed | The wrapped coil, fully covered in blue film, runs out onto the outfeed rollers |
| Operator | One operator starts the cycle and watches from beside the machine |
The coil stays flat while the ring passes through its eye, so the film covers the inside, outside and both faces in one pass round the coil.
Why eye-through wrapping for wire coils
- Full cover. Each turn of the ring goes through the eye, so the film covers the whole coil section, not just the outside.
- Rust and dust. A closed film layer keeps moisture and dust off drawn wire in storage and transport.
- Coil stays flat. The coil is supported on rollers, so there is no upending step before or after wrapping.
- Steady coil. Side protective rollers hold the coil in place while the ring turns.
FPW-AU300 data
Our published data for the automatic steel wire coil packing machine FPW-AU300:
| Item | Published value |
|---|---|
| Coil weight | 300–1,500 kg |
| Coil width | 100–300 mm |
| Coil OD | 500–1,200 mm |
| Coil ID | 300–900 mm |
| OD minus ID (published limit) | Under 500 mm |
| Roller speed | 2–4 m/min |
| Ring speed | 0–90 r/min |
| Overlap | 10–90% |
| Wrap material | Stretch film or paper, 120 mm wide, 50 mm core |
| Power | About 3.8 kW, 380 V 50 Hz 3-phase |
Supporting rollers are polyurethane covered, and ring and roller speeds are set by inverters.
Overlap and turns
Worked example (illustrative). With 120 mm wide film at 50% overlap, each turn of the ring advances the film by 120 × 0.5 = 60 mm along the coil circumference. A coil whose mean circumference is 2,200 mm then needs about 2,200 ÷ 60 ≈ 37 ring turns for one full layer.
Selection checklist
- Coil OD, ID and width, and the OD minus ID value.
- Coil weight.
- Film, paper or both.
- Overlap and layers for your transport route.
- Coils per hour from the drawing or coiling line.
- Upstream compacting and strapping, such as a steel wire coil wrapping, upending and stacking line.
Safety
The ring turns through the coil eye and the coil moves on powered rollers. We fit guardrails, soft start and stop, and a separate electrical box, and guard the ring zone to the risk assessment. For CE markets we apply ISO 12100:2010 for the risk assessment and EN 415-10:2014 for general packaging-machine requirements.
Engineering FAQ
Q: How does the machine wrap a wire coil? A: The ring passes through the coil eye while the coil turns on its rollers, so film covers the whole coil section.
Q: What coil sizes fit the FPW-AU300? A: OD 500–1,200 mm, ID 300–900 mm, width 100–300 mm, with OD minus ID under 500 mm.
Q: How heavy a coil can it take? A: 300–1,500 kg.
Q: What wrap material does it use? A: Stretch film or paper, 120 mm wide on a 50 mm core.
Q: Can overlap be changed? A: Yes, from 10% to 90%, set by inverter.
Q: How many ring turns for one layer? A: It depends on coil size; a coil with a 2,200 mm mean circumference needs about 37 turns with 120 mm film at 50% overlap.
Q: What power does it need? A: About 3.8 kW at 380 V 50 Hz 3-phase.
Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.
Next step
We size an automatic wire coil packing machine in three steps:
- Submit your layout drawing with coil sizes and weight, wrap material and coils per hour, to info@fhopepack.com.
- Receive a proposal within 48 hours with the machine data and layout.
- Book a site survey so we confirm the floor space and conveyor links.
